5. The method according to claim 1 , wherein establishing the short-distance wireless communication data channel specifically comprises: when enabling of a short-distance wireless communication function is received, detecting the object terminal which enables the short-distance wireless communication function in a preset range; and generating the short-distance wireless communication data channel to the object terminal.

6. A terminal with a touch screen, comprising: a processor; and a touch screen, wherein the processor is configured to detect a touch on a file displayed on the touch screen, determine whether an attribute of the touch meets a preset condition, wherein the attribute of the touch comprises at least one of the following: a duration of touching the file, a track of dragging the file, and a final object location to which the file is dragged, based upon the preset condition, select a short-distance wireless communication data channel from among a plurality of short-distance wireless communication data channels in communication with an object terminal, establish the short-distance wireless communication data channel with the object terminal, and transmit the file to the object terminal through the established short-distance wireless communication data channel, when the attribute of the touch meets the preset condition wherein the preset condition and the short-distance wireless communication data channel are in one-to-one correspondence with each other.

7. The terminal according to claim 6 , wherein after the determining that the attribute of the touch meets the preset condition and before the transmitting the file to the object terminal through the established short-distance wireless communication data channel, the processor further is configured to: send a file reception request indication to the object terminal; and when a file reception confirmation indication returned by the object terminal is received, perform the operation of transmitting the file to the object terminal through the established short-distance wireless communication data channel.

8. The terminal according to claim 7 , wherein the processor further is configured to detect the object terminal which enables the short-distance wireless communication function in a preset range when enabling of a short-distance wireless communication function is received, and generate the short-distance wireless communication data channel to the object terminal.

9. The terminal according to claim 7 , wherein establishing the short-distance wireless communication data channel specifically comprises: the processor further is configured to detect the object terminal which enables the short-distance wireless communication function in a preset range and generating a short-distance wireless communication signaling channel when enabling of a short-distance wireless communication function is received, and trigger generation of the short-distance wireless communication data channel to the object terminal through the short-distance wireless communication signaling channel.

10. The terminal according to claim 6 , wherein the processor further is configured to detect the object terminal which enables the short-distance wireless communication function in a preset range when enabling of a short-distance wireless communication function is received, and generate the short-distance wireless communication data channel to the object terminal.

11. A data transmission system, comprising: a processor; a storage; and a touch screen, wherein the processor is configured to when a touch on a file displayed on the touch screen is detected, determine whether an attribute of the touch meets a preset condition, where the attribute of the touch includes at least one of the following: a duration of touching the file, a track of dragging the file, and a final object location to which the file is dragged; and when the attribute of the touch meets the preset condition, based upon the preset condition, select a short-distance wireless communication data channel from among a plurality of short-distance wireless communication data channels in communication with an object terminal, establish the short-distance wireless communication data channel with the object terminal and transmit the file to the object terminal through the established short-distance wireless communication data channel; the storage is configured to store the preset condition and the correspondence between the preset condition and the short-distance wireless communication data channel, wherein the preset condition and the short-distance wireless communication data channel are in one-to-one correspondence with each other.

12. The system according to claim 11 , wherein the preset condition is at least one of the following: a duration of touching a file is no shorter than a preset duration, a track of dragging the file is a preset track, and a final location to which the file is dragged is a preset location.

13. The system according to claim 11 , wherein when the processor detects that the attribute of the touch on a screen meets a preset condition in the storage, the processor is configured to determine that a chosen file needs to be transmitted to an object terminal through a short-distance wireless communication data channel corresponding the preset condition, where the object terminal is a terminal which establishes the short-distance wireless communication data channel with the terminal with the touch screen.
